4 Electrical connection

4 to 20 mA
V
4 to 20 mA for both analog inputs
Caution:
When only one probe (SIL2) is connected, the temperature limiter device is reduced from
SIL3 to SIL2! However,
the internal 2-channel structure (1oo2D) in the device still remains.
Both channels measure the same current signal due to the simplified external wiring.
